Professor Beverley Sinclair smiled happily as she slumped back into her office chair, her legs splayed apart. Life was good. Not always, of course - most of the time, it was stressful and boring. But when she had two blonde, muscle-bound beauties kneeling between her thighs, life was good. Beverley reached out to rest one of her hands on each of their heads, stroking their long, golden hair. They giggled, and looked up at her with eager smiles.

  “Lexi,” Beverley said, addressing one of them. “You’ve been a very bad girl lately, don’t you think?”

  “I have, Professor Sinclair,” Lexi replied, her voice high-pitched and simpering. The bimbo wiggled her ass invitingly. “Do you wanna, like, punish me?”

  “I don’t think so, not today. But your grades are slipping,” Beverley admonished. “I think you’re going to have to do some extra credit for me.”

  “I’d be, like, totally happy to, Professor,” Lexi said, with a giggle.

  “Then what are you waiting for?”

  Lexi giggled again, and started leaning forward. Beverley had already let her miniskirt ride up to expose her panties, and Lexi now pulled those aside to completely expose her body to the open air. The blonde started kissing the professor along pale thighs, making an increasingly sensitive trail up to her pussy. That feeling alone was enough to make all Beverley’s stress melt away. It was a form of stress relief she’d become accustomed to by now. After her first encounter with Lexi, Beverley had sworn never to so much as go near her again. But to her surprise, she’d been unable to stop thinking about it. It had been uncomfortable, unplanned, and potentially professionally ruinous - but it had also been the best sexual experience of her life. After a month, she’d found herself taking Lexi up on her offer of a repeat. And then again, three weeks later. And again, two weeks later. Since then, it had been slowly edging closer to becoming a weekly appointment. The fiction that Beverley was making Lexi sleep with her in exchange for good grades had become increasingly absurd - they were both in it for nothing more than their own pleasure - but it helped Beverley deal with it a little easier, and besides, she’d found a little role-play could be a lot of fun.

  “And you,” Beverley continued, addressing the other girl. “You’re not in my class. What are you here for?”

  “Sorry professor,” said the other bimbo. “I just, like, can’t help myself.”

  “That’s what I thought.” Beverley was struggling to keep her voice even as Lexi’s tongue started lapping at the edges of her pussy. “You’re just a nasty slut who’s eager to be used, aren’t you Ashley?”

  “Yeah.” Ashley giggled, her face growing flushed with arousal. “I’m, like, such a dirty girl.”

  “Then is there something you want?”

  “Yeah!” Ashley nodded eagerly.

  “Then be a good girl and beg for it.” Beverley had to suppress a moan to continue to pretend to be being stern with the second bimbo.

  “Please, professor!” Ashley’s voice become high-pitched and whiny, taking on an absurdly heightened valley girl accent. “Please let me eat you out! I need it so bad! I promise I’ll, like, totally be your good little whore.”

  “Hmmm.” Beverley was tempted to draw things out a little more in order to have fun teasing the girl, but the idea of having both girls eating her out at once was too enticing to delay any longer. “Very well. You can join your girlfriend.”

  “Thank you!” Ashley said happily, and bent forward. Within moments, her face was right alongside Lexi’s, and the two girls were pushing up against each other good-naturedly, jockeying for space between Beverley’s legs so they could more easily lick her cunt. Beverely stopped bothering to hold back her moans, and a happy, horny grin spread across her face. Life was good.

  A few weeks before, when Beverley had summoned Lexi to her office for a ‘stern discussion about her grades’, she’d been taken completely surprised when Lexi had brought along another girl to join in. At first she’d protested, unwilling to let anyone else find out about what she and Lexi were doing together. But on seeing that Ashley was just as much of an eager, shameless slut as Lexi was, Beverley had been easily convinced to let Ashley participate, and since then she’d been there every time. Their wanton sluttiness wasn’t the only way the two girls were alike. Physically, they resembled each other greatly. They both had blonde hair, clearly dyed, they both wore incredibly skimpy pink clothes and had on whorish makeup, and both talked and acted like stereotypical bimbos. Neither of them seemed set to win any academic awards, to put it kindly, but they more than made up for it when it came to their sex skills. They were also both in incredible physical shape, their exposed bodies covered with rippling muscles. Ashley was a little less muscular than Lexi, and her hair was a little shorter. That was it. Beverley had initially taken them for sisters, but Lexi had introduced Ashley as her girlfriend and told her they were very much in love.

  The details of their relationship were a mystery to Beverley, but the college professor was more than happy to have another eager slut to toy with and be pleasured by. They were both hot, eager to please, and their bodies were nothing short of incredible. They were like twin bimbo amazons. Beverley had never been particularly conscious of being attracted to muscular girls before, but she certainly was now. She’d had plenty of time to explore all the rigid contours of Lexi’s body, learning how firm and strong yet sensitive she was, and appreciating all the ways that her well-defined muscles enhanced her femininity and sex appeal.

  Plus, it was an incredible power trip, having two strong, young, beautiful girls so utterly devoted to serving her. Beverley spent eight hours a day, every day, plus overtime, dealing with college brats. Most of them were more interested in sports, alcohol or sex than in their education, and Beverley often felt like the biggest part of her job was chasing after poor students, hassling them about their bad grades and missed assignments. It was frustrating beyond belief. She was meant to be an educator and a respected academic, not a glorified babysitter. Now, though, she felt like a queen. She had not one, but two bimbos licking her pussy, doing whatever they could to bring her as much pleasure as possible. As Beverley moaned, Lexi reached up to grope her tits and kiss her midriff, allowing Ashley to truly bury herself in Beverley’s cunt and eat her out to her heart’s desire. A moment or two later, Lexi pushed Ashley aside and returned to her spot between Beverley’s legs and then both of them were going at her at once, their two skilled tongues working in tandem to drive Beverley to incredible heights of pleasure. It was a treatment she could easily get used to. Increasingly, she was starting to feel as though it was what she deserved. She felt powerful. She felt good. It was exactly what she needed at the end of a long week.

  “More,” she moaned, even though she knew Lexi and Ashley didn’t need any more encouragement. Her voice cracked. “F-faster!”

  “Yes, professor!” they both replied at once, and then giggled at each other.

  Beverley felt them increase their pace, licking her pussy even more eagerly. Her back arched involuntarily as electric shocks of pleasure traveled up her spine. She was already getting close. Fortunately, she was confident it would be far from the only orgasm she was going to receive that evening.

  “Whichever one of you makes me cum gets to wear it on their face,” Beverley moaned, her eyes closing from the overwhelming bliss filling her body. “And the loser doesn’t get to cum tonight.”

  The girls made an eager noise at the first part of her promise, and whiny, fearful noise at the other. But much louder than either of was the unexpected, feminine voice that came from the doorway of Beverley’s office. “Wow, that’s quite the offer, teach.”

  Beverley’s eyes shot open, and she almost fell out of her chair from shock. Once she saw that there was someone standing in the doorway, she rushed to sit up straight and push Lexi and Ashley away from her in a feeble attempt to hide what they had been doing. Inwardly, Beverley had turned from blissfully happy to icy and terrified. Her mind was racing to think through all the implications of what had just happened. What if she’d seen everything? What if she knew what kind of relationship Beverley had with Lexi? What if she told someone? It could ruin everything. Beverley tried desperately to think of excuses, or things she could offer this stranger in exchange for their silence, and at the same time she cursed herself for being so stupid. How had been so careless?

  “I… look… this is just…” she spluttered impotently.

  The girl standing in the doorway laughed. “Save the excuses. I got it all on tape.”

  Beverley looked, and her horror was magnified tenfold when she saw that the stranger was indeed holding a video camera, and pointing in straight in her direction. Desperately trying to calm herself, she took a moment to size up the butch-looking girl. She was very tall and even more muscle-bound than Lexi, but unlike her had tanned skin and brown hair, styled in a sidecut. She was wearing tight-fitting exercise gear, and had a distinct bulge in the front of her pants. She looked intimidating, and effortlessly confident.

  While Beverley was still trying to figure out her next move, Lexi and Ashley rose to their feet. Taking the professor by surprise yet again, Lexi addressed the newcomer: “Sierra! Did we, like, do it right?”

  “You did great,” replied Sierra. “I got exactly what we were looking for. I’ll be sure to reward you afterwards - both of you.”

  “Thanks.” Lexi and Ashley both shivered in pleasurable anticipation.

  “What… what…” Beverley was so confused she could barely form words.

  “Hold that thought,” Sierra said, smirking. “I need to let mistress know.”

  She pulled out her phone from a pocket in her shorts, and tapped the screen a couple of times. Beverley just waited. She’d stopped trying to speak. Everything that happened only made her more confused. Who was this Sierra? How did Lexi and Ashley know her? Was this planned? And who the hell was their ‘mistress’? Her final question was answered just a few moments later, when yet another strange girl entered the doorway of her room. This one couldn’t have contrasted with Sierra more sharply. She was thin and her hair was jet black, and she was dressed in an impressively-ornate, black and white, gothic-style dress. Her makeup was equally impressive, and was impeccable. She looked like a dark queen out of a fairytale. Beverley couldn’t quite explain how, but she seemed exude an aura of authority and control. The others seemed to sense it too; Sierra, Lexi and Ashley all bowed their heads submissively for a moment in the goth girl’s direction when she entered the room. With a difficult-to-read smile on her face, she fixed her gaze on Beverley.

  “Good evening, Professor Sinclair,” she said. “I apologize for the interruption.”

  “I… um… allow me to explain,” Beverley began uncertainly. “This was just… um…”

  “I’m sure you have a wonderful excuse in mind,” the goth girl said. “But unfortunately for you, Sierra here has a record of everything. Thank you for that, by the way. Good girl, Sierra.”

  The tall, athletic girl twitched abruptly, and the bulge in her pants shifted as a blissed-out expression passed over her face for a moment. Beverley blinked in surprise. Had Sierra just cum?

  “But where are my manners?” the goth girl continued. “I haven’t introduced myself yet. My name is Winter, I’m a student here.”

  Winter. Beverley wasn’t familiar with the name. She’d have to do some research later. For now, though, she needed to focus on defusing the immediate situation. It was obvious what Winter intended: blackmail. “What do you want?”

  “I’m glad we understand each other so well,” Winter said. “This footage wouldn’t go down very well with the dean, would it? You know, I was very surprised when Lexi told me about all the fun you two had been having together. I thought to myself: what a waste it would be, to let someone in your position slip through my fingers! I can think of all sorts of uses for someone like you.”

  Yes, blackmail. Beverley swallowed awkwardly. She hated the thought of letting this girl intimidate her, but she felt completely backed into a corner. “I-I have money.”

  “Money? Oh no, Professor Sinclair, you misunderstand.” Winter’s smile grew a little wider. “I don’t want money. I’ll be happy to turn this footage over to you for free. All I want in exchange is for you to play a little game with me. That’s all. Just a little, harmless game.”

  “A game?” Beverley squinted at the goth girl. It seemed like an obvious trick, but she couldn’t see how. She supposed it was better than a demand for money. “Fine.”

  “Excellent! May I sit?” Winter didn’t wait for an answer. She walked across the room and sat down in a chair on the opposite side of Beverley’s desk. To Beverley’s surprise, she reached a hand down the front of her own top, fishing around for something. “Let me explain how it works. It’s very, very simple.” Pulling her hand out, Winter retrieved what seemed to be a silver pocket watch, held around her beck by a chain. Winter held it up by the chain in the air between them, allowing it to swing slowly side-to-side. “See the watch? See the way the second hand ticks?”

  Beverley could see, and she could hear the steady tick-tock of the intricate clockwork cogs inside the watch, keeping time. “What’s the game?”

  “The game? It’s easy. Nothing to worry about.” Winter’s smile grew wider still. “All you have to do is stare at the watch, and make the second hand stop.”
